A Water and Wastewater Utility Guide to More Sustainable Energy Management Presented by Peter V. Cavagnaro, P.E., BCEE Johnson Controls, Inc. Prepared by Alicia Chakrabarti, P.E. East Bay MUD Barry Liner, PhD, P.E. Water Environment Federation MWEA June 24, 2013
Change our Mind(set) WEF believes that wastewater treatment plants are NOT waste disposal facilities, but rather water resource recovery facilities that produce clean water, recover nutrients (such as phosphorus and nitrogen), and have the potential to reduce the nation s dependence upon fossil fuel through the production and use of renewable energy.
Energy Summit Raleigh, NC March 28-29, 2012 30 invited participants from the water and power industries Outcome Energy Roadmap
Energy Roadmap Purpose To help utility managers effectively plan and implement efforts to enhance energy sustainability Build off of the wealth of existing information
Energy Roadmap Structure
Energy Management Matrices The core of The Energy Roadmap
ENABLE INTEGRATE OPTIMIZE Strategic Management Organizational Culture Communication and Outreach Demand Side Management Energy Generation Six Topic Areas with Three Levels of Progression Innovating for the Future
ENABLE INTEGRATE OPTIMIZE Strategic Management Organizational Culture Communication and Outreach Demand Side Management Energy Generation Innovating for the Future Each Spot on the matrix contains content developed during the Energy Summit and explained in the guidance document

STRATEGIC MANAGEMENT
Strategic Management Strategic Direction Financial Viability Collaborative Partnerships Towards Carbon Neutrality Energy Use Time Possible Goals 75% energy produced onsite 20% energy conservation 90% energy from renewables 50% employees on public transportation
ORGANIZATIONAL CULTURE
Organizational Culture Energy Vision Energy Team Staff Development & Alignment ENERGY VISION Elected Officials STRATEGIC PLAN Utility Leadership Group/Management PERFORMANCE PLANS Staff Staff Staff Staff Staff Staff
Organizational Culture Energy Vision Energy Team Staff Development & Alignment Engineering Staff Planning Staff Operations Staff Energy Champion Maintenance Staff Regulatory Compliance
Organizational Culture Energy Vision Energy Team Staff Development & Alignment Training Understanding electricity understanding energy management Energy billing, peak demand Lifecycle cost analyses Industry Information Sharing Rewarding Conservation Incentives
COMMUNICATION AND OUTREACH
Communication and Outreach Customers and Community Regulatory and Legislative Media Outreach Environmental Advocacy Groups Water Sector Identify target stakeholders Tailor the approach Evolve and grow efforts Tips: Be proactive and create the story Emphasize the project benefits (stakeholder specific) Share lessons learned within the sector
DEMAND SIDE MANAGEMENT
Demand Side Management Electricity Costs and Billing Power Measurement & Control Energy Management Source Control Review Data 2 years of bills Analyze Costs Energy charges Demand charges Rate structure Make Changes Rate structure Shift loads
Demand Side Management Electricity Costs and Billing Power Measurement & Control Energy Management Source Control Analyze Baseline Energy Use Benchmarking by Process Real-time control Anaerobic Digestion (12%) Activated Sludge (51%) Lighting & Buildings (10%) Solids Handling (8%) Pumping (15%) Primary (3%) Other (1%)
Demand Side Management Electricity Costs and Billing Power Measurement & Control Energy Management Source Control Energy Audit Implement Changes Incorporate Energy into Future Designs Reduce Energy Use of Key Equipment By: Shutting down Operate part time Operate with variable speed Operate at lower flows Operate at lower pressures Replace with more efficient equipment
Demand Side Management Electricity Costs and Billing Power Measurement & Control Energy Management Source Control Understand Influent Loading Manage Loads to Reduce Energy Use Reduce Inflow/Infiltration Industrial surcharges Manage Loads for Energy Production Incentives for trucked high-strength waste
